Biosensors for Health and Environmental Monitoring

Associate Professor of Chemistry & Biomolecular Science Silvana Andreescu is currently working on biosensors for environmental and clinical monitoring.

A biosensor is a device that detects, records and transmits information regarding a physiological change or the presence of various chemical or biological materials. Biosensors integrate a biological component, such as an enzyme, with an electronic component to yield a measurable signal.

Andreescu's research group is developing implantable enzyme microbiosensors to monitor changes in neurotransmitters like dopamine, serotonin and glutamate that may signal an onset of disease.

"We are looking to construct devices that could be used by researchers to study biomolecular mechanisms at cell and organ levels and by physicians for the early diagnosis of disease," explains Andreescu.

Andreescu has also received support from the National Science Foundation (NSF) to develop bionanotechnology laboratory experiments to revamp the chemistry curriculum by implementing new and emerging technologies in the undergraduate teaching labs. She has published more than 50 peer-reviewed journal articles and 11 book chapters, has co-edited one book, has three patents, and has delivered some 100 presentations at professional and academic conferences throughout the world.

Andreescu has managed external research funding totaling about $1.3 million from the NSF, New York State Energy Research and Development Authority (NYSERDA) and several other funding agencies. In 2010, Andreescu received the NSF CAREER Award, the NSF’s most prestigious award for junior faculty.
